E-commerce KYC: data-driven anti-fraud, demonstrated 220:1 ROI

> In short. Online fraud eats up to 3% of an e-retailer's revenue. We verify the identity of your buyers and your marketplace sellers in real time by cross-referencing transactional, government, telecom and media data. You cut card fraud and chargebacks without weighing down the checkout flow. PSD2 (3-D Secure), GDPR and DSA compliance embedded. Because today, everything can be forged — except real life and what people actually buy.

The real cost of e-commerce fraud

Online fraud has reached an industrial level. Four statistics summarize the stake you face.

E-commerce fraud stakes in numbers

Indicator Value
of average revenue lost to fraud each year 3%
spent for every euro defrauded (chargeback, investigation, operating costs) €3.64
in annual global losses for e-commerce $41B
in annual fraud in France €1.1B

 

Sources: sector studies on e-commerce 2023-2025, ACPR (French prudential authority) annual reports, Banque de France. E-commerce has become a prime target for identity theft, credit-card spoofing and takeover of existing accounts. We see this phenomenon accelerate as synthetic-identity generation tools spread.

Worth noting. The ratio €3.64 per €1 defrauded means that fraud mechanically brings more ancillary costs than the direct loss. Banking fees, dispute management, team demobilization, degradation of the legitimate customer relationship: online fraud is a hidden cost item that you probably underestimate today.

Why KYC has become critical in e-commerce

Online payment democratized far faster than identity verification means. The generalization of buy-now-pay-later (BNPL), multi-vendor marketplaces and financial services embedded in e-commerce platforms has multiplied the attack surfaces. KYC (Know Your Customer, customer identity verification) is no longer optional to protect yourself.

PSD2 (the EU payment services directive) imposes strong customer authentication at the moment of payment, technically delivered through 3-D Secure (3DS). But this authentication only validates possession of the payment instrument — it does not verify the real identity of the buyer. To fight document fraud, synthetic identity and impersonation, data-driven e-commerce KYC has become indispensable. Source: ACPR, EBA PSD2 guidelines.

Four critical e-commerce use cases

This necessity particularly affects four use cases you probably encounter.

CASE 1

Marketplaces

You verify the identity of B2C/B2B sellers before listing (DSA, Digital Services Act, requirement).

CASE 2

BNPL and instant credit

You apply mandatory KYC above €200 and document compliance with AMLD6 (the 6th EU Anti-Money Laundering Directive).

CASE 3

Sales above €200

You limit the risk of fraudulent chargebacks and card repudiation.

CASE 4

Embedded financial services

You secure payment, micro-credit and affinity insurance.

Our eIDV (electronic identity verification) intervenes upstream of document friction. The majority of your customers are identified without uploading a document. Only at-risk profiles or those that cannot be identified that way trigger a complementary document request.

E-commerce use cases

A new customer creates an account on your site. In the background, our API queries transactional, government, telecom and media sources in under one second to confirm the real existence of the profile. The majority of sign-ups are validated without visible friction. Uncertain profiles trigger targeted document verification — not the whole flow.

For high-value orders, or for a recent customer, you gain by triggering identification at order time to reduce chargeback risk. Our setup integrates natively into your online payment funnel: less than 800 ms latency per call, compatible with your 3-D Secure orchestration.

BNPL players must apply full KYC above €200. Our solution combines identity verification, sanctions screening and risk scoring in a single API call. The purchase journey stays fluid, AMLD6 compliance is documented at every step.

For marketplaces, the Digital Services Act (DSA) requires verification of the identity of every seller, individual or professional, and their traceability over time. We integrate KYB (Know Your Business, identification of seller companies) verification and the identification of beneficial owners. You document your DSA obligations without slowing down the enrollment of your seller partners.

Anonymized case. A French marketplace platform deployed our eIDV across its 50,000 annual new sellers. Fraud rate divided by three in six months, DSA compliance documented, sign-up drop-offs reduced from 22% to 8%.

ROI modeling on a typical e-commerce setup

The economic case for eIDV is striking. Take an online merchant that acquires 100,000 new customers a year.

IndicatorValue
Annual new customers100,000
Fraud rate without eIDV (3%)3,000 fraudsters
Average fraud cost€150
Annual fraud losses€450,000
eIDV cost (€1.50 × 100,000)€150,000
Net annual gain on new customers€300,000

On the existing client base (600,000 recurring customers with a 3% fraud rate and an average cost of €150), the net gain reaches €1.8 million per year. Overall, the documented ROI on eIDV deployments in e-commerce commonly exceeds 220:1, in line with the cases observed on online banking.

ROI calculation. For a mid-market European e-commerce player, the deployment of our data-driven verification pays back in under three months. You measure the ROI trajectory from the pilot phase — that is our commitment.

Our data approach for e-commerce

Our conviction is intact: "Because today, everything can be forged — except real life and what people actually buy." A bank card can be stolen, a password phished, a selfie deepfaked. But an individual who pays their energy, rent and mobile subscription at the same address for three years cannot be invented.

We verify identity through data from verified purchase transactions, backed by government, telecom and media sources.

  • Transactional: verified purchase activity, address tenure, tax household
  • Government: official registries, sanctions lists, PEP databases
  • Telecom: number reliability, subscription tenure
  • Media: editorial and professional presence, name/address cross-checks

Our approach is a necessary complement to the other KYC layers (biometrics, document checks) — not a replacement. Whether you wish to keep a document layer or switch to a frictionless mode, our eIDV plugs in upstream and turns document friction into an exception rather than a rule. The technology integrates into your existing anti-fraud system. To dig deeper, you can explore the overview of KYC & eIDV solutions.
